摘要： Vanadium and titanium values are recovered from vanadium containing titaniferous iron ore by subjecting the ore to a reduction process to separate the iron from the slag containing the vanadium and titanium, fusing the slag with an alkali metal salt, oxidizing the vanadium to its plus five oxidation state, and recovering the vanadium and titanium by conventional techniques.
